For as long as I can remember, I've been having issues with scrolling in Windows and its applications. When scrolling via dragging the scroll blob, it seemed as if Windows had the annoying habit of randomly resetting your scroll blob to its starting position, which irritated me to no end. It took me a while to figure out, but I finally know when this behaviour occurs - now I just need to know: why?!

Also.. LXDE, FluxBox, OpenBox, BlackBox, and XFCE do not exhibit any of these issues either.
I'm unable to confirm for Gnome.. I stopped using Gnome because of its inclusion of the Mono code. So, there you have it.
